I bet the answer to this is going to be one of those "duh" answers, but I can't seem to figure it out. Using my D200, every time I reformat it starts my file naming back at 001. This is a bit problematic because when I go to put the photos in the desired folder on my computer hard drive, there are already duplicate images with the same name. It used to be that the file naming was sequential no matter if I reformatted or not (the image number/name would just get higher). This way I would never have a duplicate image name (unless it was taken with a different camera). When I go into the menu on my D200, I see an option for "file naming" but it only appears to let me change the beginning of the file name (DSC letters, not the number). There is another option called "folder" that is set at 105, but I don't even know if that is related. It will number as many images as my card will fit (762 on my biggest card). But, when a new card goes in, it starts back at 001. Any suggestions?
